BTTF free DVD

I'm still eligible for a free BTTF DVD after ordering the series (at least, I hope so). Unfortunately, I don't have the notification e-mail any more. Is there any way to order the free DVD from the website (similarly to the TWAU DVD), or could you re-send the link to claim the DVD to me?

There unfortunately never was a free Season 1 TWD Collector's DVD like there was with Sam&Max S1-3, TOMI, Wallace&Grommit, BBTF, Strong Bad, TWAU or TWD S2 the only existing DVD of this game is the retail DVD. It is sad but the truth.
